# Shadow Vault

> Shadow Vault is a privacy-first Android app that archives device notifications locally with SQLCipher encryption. Read every message on your terms — no read receipts, no "last seen" updates, no cloud, no account, no tracking.

Shadow Vault captures notifications from any messaging app (WhatsApp, Discord, Slack, Telegram, Signal, LINE, Messenger, and more) and stores them in an encrypted local database. Users can read messages without ever opening the source app, avoiding read receipts and online status updates. The app is secured with PIN or biometric authentication and includes full-text search across all archived messages.
